Dr Brown's Natural Flow Polypropylene Bottle, Pack of 2, 240ml

Product information

A pack of 2 Natural Flow 240ml Baby Bottles from Dr Brown.

The patented system with an internal vent is designed to create a 'vacuum-free' environment. This eliminates the air bubbles found in most baby bottles. It allows air to enter through the teat collar, without being incorporated into the breast milk or formula. The air is then channelled through the internal vent system, to the area behind the feed.

Babies are able to feed more comfortably because the vent allows babies to feed without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This reduces colic, burping and wind. The breast milk or formula flows freely through the teat as the air is channelled to the top of the bottle. This no-vacuum effect eliminates teat collapse.

Q & As

Rated 4.3 out of 5 by 9 reviewers.
Rated 5 out of 5 by Fantastic bottles for 3month old baby with reflux Our 3month old baby suffers from silent reflux and feeding became a very negative experience. He was very windy & cried during/after every feed. We were previously using Avent bottles & having to wind our baby after every 1oz he drunk. We noticed a significant difference in the amount of milk our baby would drink and his comfort after the first 24hrs of using these bottles. He is so much less windy and he hardly swallows any air due to the vacum system these bottles provide. My only regret is not buying these bottles sooner!!! 02 June 2015
Rated 1 out of 5 by Damaged-So disappointed!!! Tear on teat!!! The milk leaked on my first attempt at the feed and thats when I realised that the teat is damaged. Such a shame as didn't expext this from a John Lewis store and now I cannot return as I washed the bottles before use! 22 September 2014
Rated 5 out of 5 by useful for beginning feeds and growing feeds adaptable with different sized teats and useful to load 8oz (2 feeds for new baby on 4oz). useful, easy and no worrying about trapped wind. comes with bottle cleaner, which is metal so a bigger bottle cleaner maybe wanted. cheap for the amount of times they will get used especially if you fill up 8oz for new baby and use on two seperate feeds (not ideal to leave formula made milk in the bottle for long periods of time, however breast feeding milk is fine to use and leave if heading out on the town and leaving with a babysitter for a few hours/evening) 22 April 2014
Rated 4 out of 5 by Dr Browns bottles for colic Bought these as having trouble with wind and colic, they seem to help but we changed a few other things at the same time, dont really have a problem with the number of bits that need cleaning like some of the other users but would like the numbers/measures on the side to be easier to read. Would buy again and recommend to parents with colic problems. 19 September 2012
Rated 5 out of 5 by Dr Brown's Natural Flow Polypropylene Bottle My Little boy was suffering from colic and was having issues winding after feeds, since buying these bottles from john lewis he has not had colic and is a much happier boy, I read comments about the different parts to the bottle but this is not an issue with the cleaning at all, I have recommended this to all my friends and would definately buy again, excellent product 27 July 2012
Rated 4 out of 5 by great I used the smaller ones of these when my baby was little. These bottles are great and do what they say... but a bit fiddly to put together with one hand! Need some sort of special brush to clean the bit at the neck of the bottle. 02 May 2012
Rated 5 out of 5 by Wonderful Having persevered with Tommee Tippee for many months (baby suffered from colic/reflux and generally refused the bottle after typically 50ml)... I finally listened to the advice from others and ordered Dr Browns bottles. I almost cried when she drank the whole bottle without pain or wind and felt awful for not swapping brands earlier! Teat is softer in her mouth and bottle design must be between - as less/no air enters the bottle/milk. They also just about fit within my TT sterilised and bottle warmer - so no need to replace the whole kit. 18 April 2012
Rated 5 out of 5 by Great for Colicy babies There is no cure for colic but these definately helped our little one. Tip: If using a colic formula you will need faster flowing teats otherwise they get blocked resulting in angry/sad baby with worse wind! 04 November 2011
